Answer:
The average rate of change is 8.
Step-by-step explanation:
The formula to calculate the average rate of change of a function F(x) is:
In this case, F(x) = 
a=2 and b=4
You have to evaluate x=2 (which is a in the formula) and x=4 (which is b in the formula) in the function.
In order to obtain F(b) and F(a) you have to replace x=4 and x=2 in the given function:
F(b) = 
F(a) = 
The answer is 8.
Basically a proportion so it’d be 1in/300 mi = 3in/x mi
cross multiple that out and you get 300•3=x and then just solve for x. the answer should be 900 miles.
Answer: y=1x + 1
i used the coordinates (-1,0) and (3,4) to find the slope 4/4 or 1.
plugged in M and B using the coordinates and got
4=1•3+b
4=3+b
-3 -3
1=b
y=1x+1
hope this makes sense!!
